ATTORNEY 2,794,252 RAZOR BLADES FGR USE IN AFETY RAZQRS Ilanos Qscar Plesch, Monti-aux, Switzerland, assignor to Peter Hariolt Plescll, Keeie, England Application Huly 6, 1954, Serial No. 441,445 Claims priority, application Great Britain .luly 7, 1953 1 Qlairn. (Cl. 30-351) Various constructions of safety razor are known which are adapted to operate with two or more razor blades arranged in tandem so as to give a closer and better shave than is obtainable when using a razor fitted with only one blade. A disadvantage of these known safety razor constructions is that they are more complicated than razors designed to operate with a single blade and take longer to assemble and dismantle.

It is an object of the present invention to enable the better shaving properties of a multi-bladed razor to be achieved, while at the same time avoiding the abovementioned disadvantages.

A further object is to enable two or more blades to be used in suitably spaced relationship in most conventional safety razors.

Yet another object is to make provision for the cutting edges of two or more safety razor blades to operate closely spaced one behind the other, by a spacing which varies from one end of the blade to the other, and to arrange the cutting edges of the two blades at different angles so that at least one cutting edge will have a slicing action.

The spacing member may consist of a metal plate which is welded or stuck by an adhesive to the associated blade or blades. Alternatively, it may consist of a strip of resilient material, such as india rubber, synthetic rubber or a like synthetic plastic composition, which is bonded or stuck by an adhesive to the associated blade or blades.

The invention is illustrated by way of example with reference to the accompanying drawings, in which:

Figure 1 is a plan view of a two-blade assembly according to my invention, and Figure 2 is a side elevation of Figure 1.

In the blade assembly shown in the drawing, two blades 31 and 32 of the assembly have their cutting edges 34 and 35 disposed at a small angle to one another as seen in atent O "ice plan, blade 31 having a smaller width than blade 32, and the two blades being spaced apart by a resilient or flexible spacer plate or layer 43, having its edges set back from the cutting edges of blades 31 and 32. The cutting edges 34 of the narrower blade 31 lie directly over the cutting edges 35 of the wider blade 32 at diametrically opposite corners 36 and 37 of the assembly. This arrangement ensures that at least one blade will operate to give an oblique out when shaving.

As shown in Figure 2, the layer 43 tapers in thickness from one end of the blade assembly to the other, so that the operative spacing between the cutting edges of the two blades 41 and 42 progressively increases from one end to the other. The ideal spacing varies according to the length, stiffness and angle of the hairs to be shaved, all of which vary in difierent facial areas, and the arrangement illustrated in Figs. 1 and 6 is designed to render available the required range of spacings to suit such different facial areas.

I claim:

A razor blade assembly, comprising a first flexible razor blade having a cutting edge, a second flexible razor blade having a cutting edge, and a flexible spacing member arranged between and alfixed to said first and second razor blades in face-to-face relationship, and dimensioned and located so as to leave the cutting edges of said blades free and unobstructed, said spacing member tapering from a small thickness at one end of the blade assembly to a greater thickness at the other end thereof so that the operative spacing between said cutting edges of said first and second blades progressively increases from said one end to said other end, and the cutting edges of the two blades being disposed at an angle to one another as seen in plan.
